Confirm Update Activity

Press MOD key → Software Version Info to check if a recent software update occurred. Compare displayed version with previous known version.

TNC controls always create timestamped backups during updates. The filename in '%3' typically includes a date/time stamp.

Verify Data Object Integrity

Access the data object type indicated in '%1' (e.g., if 'Tool Table', press TOOL TABLE key; if 'Preset Table', press POS key). Verify all entries are present and correct.

After updates, the control may migrate data formats. The moved file represents the pre-migration version.

Locate and Document Backup

Press MOD → File Management, navigate to the path shown in '%3'. Note the backup file location and size for future reference.

Standard backup location is typically TNC:\system\backup\ or TNC:\backup\ depending on control generation.

Test Machine Operation

Perform a dry run test of a known program to verify tool data, offsets, and presets function correctly with the current active data objects.

Use dry run mode with feed override at 0% initially to verify correct tool selection and offset application.

Check System Event Log

Press MOD key → System Information → Event Log. Review entries immediately preceding alarm 140-0034 for error messages related to file system, checksum failures, or data corruption.

Look for alarm codes in the 13x-xxxx or 14x-xxxx ranges that indicate file system issues.

Inspect Moved File Contents

Use MOD → File Management to navigate to '%3' backup location. If file is ASCII (*.tab, *.d, *.h), open with internal editor to check for garbled data or unusual characters.

Do not modify backup files directly. Only inspect for diagnostic purposes.

Verify Current Active Data

Compare current active data object with the backup file. Check critical parameters: for tool tables verify T numbers, lengths, radii; for presets verify X, Y, Z values against machine documentation.

Export current active table to USB using File Manager and compare externally if large datasets are involved.

Restore from Backup if Needed

If current data is incomplete or incorrect, copy the backup file from '%3' location back to its original location. Use File Manager copy function with confirmation prompts enabled.

Always create an additional backup copy to USB before overwriting any system files.

Check Hard Disk Health

Navigate to MOD → System Information → Memory Info. Check available disk space and verify no errors reported. If disk usage >90%, perform cleanup of old NC programs and log files.

Consistent file corruption may indicate CF card or hard disk failure. Run disk diagnostics if issue recurs.

Verify Recent User Actions

Check with machine operators if any MOD function reset operations were performed. Review operator log or shift notes for documentation of intentional changes.

Access MOD → General Settings → Password Settings to verify which user account performed the action if multi-user mode is enabled.

Compare Backup with Current State

Open backup file from '%3' location and compare with current active data. Determine if reset was complete or partial by checking record counts and entry values.

Tool table backups: check number of tool entries. If backup shows 200 tools but current shows 0, a full reset occurred.

Restore from Backup if Required

If reset was unintended, navigate to backup file location in File Manager, select the file, press COPY, navigate to original location (e.g., TNC:\table\), and paste with overwrite confirmation.

After restoring tool table or preset table, cycle control power to ensure proper initialization of restored data.

Implement Access Control

If reset was accidental, configure password protection for critical functions. Go to MOD → General Settings → Password Settings and enable protection for 'Machine Parameters' and 'Table Access'.

TNC 620/640 controls support multi-level user permissions. Create operator-level accounts with read-only access to critical tables.
